Tengu-jin

Tengujin is a story about two twin brothers who live in a slightly futuristic Japan where the Eastern and Western regions are splitting apart and have formed two warring nations. When Gods of the world, mainly tengu, seek to influence the start and end of the events that lead to war, the younger twin, Mozuku, desires to end the idiotic war and meets with the God of the West, Sai, with his older brother, Shinonome.

"Zanouka," the second story in Tengujin, is about the former incarnations of Mozuku and Shinonome.
